PHARMACOGNOSTIAL EVALUATION AND PHYTOCHEMICAL SCREENING OF THEVETIA PERUVIANA
Flowers of Plant Thevetia peruviana (Pers.) K. Schum.were reported to possess good medicinal value in traditional system of medicine, the present investigation deals with Macroscopic, Microscopic and preliminary phytochemical investigation of flowers of Thevetia peruviana which includes pharmacognostical parameters, physiochemical parameters like ash values, extractive values and moisture content. The total ash, acid insoluble ash, waterâ€soluble ash values and sulfated ash were observed to be 3.50%, 1.60%, 1.30% and 1.20% w/w respectively. Alcohol soluble, waterâ€soluble and Ether soluble extractive values of the flowers were observed to be 8.30%, 4.80%, and 3.70% respectively. Powdered flowers were also subjected to fluorescence analysis with different chemicals. Phytochemical investigation of powdered drug revealed the presence of Alkaloids, glycosides, tannins, phenolic compounds, proteins, essential oils, gums, mucilage and fixed oils. The main aim of the present investigation is to study the macro, microscopic and some other pharmacognostic characters and physicochemical standards of flowers of Thevetia peruviana Pers. which could be used to prepare a monograph for the proper identification of the plant.
